uneven loft

[pc-6]

For the first piece of this part I require a simple oval to be lofted to a circle. The loft comes out uneven and I do not understand why. This is very visible if you view the part from the end profile as in the attached screen shot. I have tried checking of the minimize twist and simplify surface, but this does not seem to help.
What am I not doing correctly?

Thanks everyone for the help.

I think this is ok. I made it in halves, I don't know why it seems to work better.

Leif.
If you look at your loft with highlighted edges on, you see a line from the oval to the cirkel, this cause the trouble.
The oval has a points to start this "edge" but there are no points at the cirkel.
Alibre then pick a point at the cirkel, this happen often when a cirkel is in a loft among other profiles.
Use guide lines to control the form.
The part looks simple, but you need to tell Alibre what you want, else Alibre make an "intelligent" guess.
